IMPROVED DlSTlLLING APPARATUS,

Specification forming part of Letters Patent No. 39,635, dated August 25, 1863.

To a/ZZ whom it may concern,.-

Beit known that I, HENRY G. DAYTON, of Maysville, in the county of Mason and State` of Kentucky, have invented certain new and useful Improvements in Distilling Apparatus; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a plan of my improved apparatus. Fig. 2 is a vertical section of the same at x x. Fig. 3 is a vertical section of the same at y y.

Similar letters of reference indicate corre- 'Ihe primary object of this invention is to produce an apparatus which can be advantageously used for distilling in copper vessels with mineral coal with great uniformity and without danger-of scorching or otherwise inj ur'- ing the liquor; and the invention particularly consists, iirst, in a peculiar construction and combination of double still and boiler for heatingthesame; second, in apeculiar construction of single still7 heatedby steam applied in a central pipe and surrounding jacket,as hereinafter described; third ,in a peculiar combination of devices to effect the economical heating of the aforesaid single still; fourtl1,in combining with the said boiler and still a boiler for heating water for mashing or other purposes,which boiler may be heated by the waste heat escaping from the furnace of the first In order that others skilled in the art to which my invention appertains may be enabled to fully understand and use the same, I

operation.

A A may represent the external walls of the furnace, in the upper part of which is The fire-box1 `is composed of hollowr walls C, in closing water-spaces, which communicate with the upper part of the boiler through legs c e c2 of any suitable number and form. p

D D D represent hollow grate-bars adaptedf to contain 'water and communicating at their respective ends with the water-spaces within the walls C C.

`E represents the hre-door, and F the dischargelue. The latter may deliver into a `,mashing grain or other purposes.

drum, G, within which is an auxiliary boiler, H, which may be employed to heat water for The heat of the products of combustion having been thus employed to the greatest possible extent, they\are finally discharged through the upper iiue, F. Water may be introduced to the boiler H through a pipe," I, provided with a suitablecock or valve, anddrawn off through a pipe, I', by means of the cock t. Y

J represents the feed-port of the boiler B, which port is closed at will by means of a valve, j, or other suitable device.

The doubling still K is constructed of copper, and is placed centrally within the boiler B, so as to be heated by means of the water and steam contained therein. The single still L (also formed of copper) is placed within an external casing or shell, M, constituting a surrounding steamj'acket. The beer in the single still L is heated by steam from the boiler B, rising through a goose-neck, thence descending through a pi e or drum, within the single still, aldlingtlsr rounding jacket M, from whence surplus steam may be taken through a pipe, I), to a feedwater heater of any suitable construction for the heating of water to supply either of the boilers B or H. The pipe Pis provided with a stop-coek, p; by which it may be opened or closed at will. n represents a cock by which the heating apparatus of the single still Kmay be shut off from the main boiler E whenever needful.

The hoods R R, conducting-pipes S S', and condensing-coils (the latter not here represented l1nay be in any of the known forms, and do not require specific description.

rllhe single still L may have a capacity of, say, two hundred and fortyr gallons, and the double stillof one hundred and twenty gallons, or in about that proportion.

The operation is as follows: Beer is first placed in the single still L, and there evaporated by the heat of steam within the central )i e, O, and jacket M. The spirituousvapor passing over through the hoodRand conducting-pipe S is condensed in any suitable and customary manner. By means of the cocksn and p the pressure and consequent heat of steam within the central pipe or drum, O, and surrounding jacket M may be regulated as the Work may require, and if there be any superuity of steam it maybe used, as before stated, for heating Water, or other purposes. The spirit thus produced is placed in the doubling still K, Where it is again distilled by' heat imparted by the Water and steam in the boiler B. The construction of the said boiler is such as to expose a large extent of fire-surface, and thus employ the heat of the furnace to good advantage, and any heat which Would other- Wise be lost is used to heat Water in the auxiliary boiler H for mashing grain, or other purposes.

From the above description it will be apparent that the entire dstilling operation is effected Without any direct contact of the re against copper surfaces. rEhus the heat is always uniform and never excessive, all danger of scorching or otherwise injuring the liquor is avoided, and Vomiting of the still is effectually prevented. No contact can occur between the steam and beer. Fuel and heat are economized as far as possible by using one lire for three purposes, and by employing the Waste steam, as before explained. The result is that lthe greatest possible amount of spirit of the finest quality may be produced from a given quantity of beer without risk of loss.

The construction and arrangement of the apparatus protect the iiuids in process of distillation from danger of contact with the iire, and

for this reason the invention is of great value for the distillation of turpentine, alcohol, and other highly iniiammable liquors.

Having thus described myinventiomwhat I claim as new therein, and desire to secure by Letters Patent, is-

l. The combination of the boiler B and double still K, both constructed, arranged, and operating in the manner and for the purposes specified. e

2. The single still L, constructed substantially as described, and heated by a central steam-pipe and surrounding jacket, as specified.

3. The described combination of the single still L, with the boiler B, of the double still K, whereby the steam', after heating the double still, may be employed for heating the single still, as explained.

4. The combination of the mash-boiler Hi The above specification of my improved d istilling apparatus signed this 14th day of May, 1863.
